Abstract :
This paper presents a new Adaptive Modulation Control (AMC) method which has proven to be very effective in achieving high bandwidth designs. AMC is a type of nonlinear control since it works only during large dynamic load transitions. Influence of AMC in both the time domain and frequency domain is analyzed. Simulation results and experimental data are included to show a very high bandwidth as well as excellent transient performance.
